Fix is_release_profile Logic

[LeWimbes]

This PR addresses two bugs in the is_release_profile function:

1. When using the default release profile, the function returned false because the loop was never entered.
2. The function never explicitly checked if the current_profile_name itself is "release".

With this patch, we:

• Immediately return true if profile == "release".
• After following an inheritance chain, also return true if we ever encounter "release".

Closes #4018.
